A researcher is conducting a chi-square test for independence to evaluate the relationship between gender and preference among three different designs for a new automobile. Each individual in a sample of n = 30 males and n = 30 females selects a favorite design from the three choices. If the researcher obtains a chi-square statistic of 2 = 4.81, what is the appropriate statistical decision for the test?
 
  A) Reject the null hypothesis with  = .05 but not with  = .01.
  B) Reject the null hypothesis with either  = .05 or  = .01.
  C) Fail to reject the null hypothesis with either  = .05 or  = .01.
  D) Fail to reject the null hypothesis with  = .10.

Question 2

  A) The researcher can reject the null hypothesis with  = .05 but not with  = .01.
  B) The researcher can reject the null hypothesis with either  = .05 or  = .01.
